I cant solve this problem: Create a for loop that logs the numbers 4 to 156 to the console. To log a value to the consol


var number = 4;
for (var i = 1; i <= 156; i += 1) {
  number += 1;

Your approach is a clever one, but I can see the reason for confusion. your number starts at 4 and should stop at 156, therefore the loop should go for 152 times. So your if statement should be

for (var i = 1; i <=152; i++) { console.log(number); number += 1; }

another approach could be for (let i = 4; i <= 156; i++) { console.log(i); }

note: let is a new way to declare variables in JS, it works as var would.

for (var i = 4; i < 157; i++) { console.log(i); }

but yeah let is similar to var and const is how to set a var that won't(can't?) be changed // constant
